n3k will also report this if you use the wrong speed transceiver in the
port.  But in this case it looks like either you've got the wrong type
of DAC connected, or the DAC has been encoded incorrectly, or nxos
screwing up the media capabilities detection:

this suggests incorrect cable or incorrect cable coding:
